Estimation of total Outgoing Longwave Radiation (OLR) flux from geostationary meteorological satellite infrared window radiance
Abstract
Total outgoing longwave radiation (OLR) flux, thermally emitted from the earthatmosphere system, was estimated by applying linear regression equations relating OLR flux with Geostationary Meteorological Satellite (GMS) infrared window radiance. The coefficients of the regression equations were determined from the results of radiative transfer model simulation with various atmospheric conditions. OLR radiances were calculated for 140divided longwave spectral intervals with 140 atmospheric conditions at eight zenith angles. A rather high correlation (R = 0.971) was found between the total OLR flux from radiative transfer calculations and estimated ones from GMS infrared window radiance, although there were low correlation regions corresponding to absorption bands (e.g., water, vapor, carbon dioxide, ozone).
